# Nijinsky’s Psychosis-Era Diary Shows a Mind Collapsing Around Three Words

*A computational analysis of the great dancer’s six-week diary finds a mechanical ‘fake coherence’ built from repetition*

## In brief

- Dancer Vaslav Nijinsky, diagnosed with schizophrenia in 1919, kept a diary during six weeks of psychosis
- Book-length texts written during an active psychotic episode are extremely rare, researchers say
- The diary was compared against a foreword by Nijinsky’s wife Romola, who had no psychiatric history
- Analysis found repetitive circling around ‘I,’ ‘God’ and ‘love,’ producing what the team calls a fake, mechanical coherence
- The results suggest psychosis can shrink vocabulary while broader narrative structure survives

Vaslav Nijinsky was called the “god of dance” — the star male dancer and choreographer of the celebrated Parisian Ballets Russes, and one of the most renowned dancers of the 20th century. His career ended early and brutally. Diagnosed with schizophrenia, he was institutionalized in 1919 and spent the last three decades of his life in and out of asylums. Somewhere in that cataclysm, during six weeks in the grip of psychosis, he kept a diary. It is now the subject of a new study examining what mental illness does to language.

Diaries of this kind are almost nonexistent. “Language provides a window into someone’s mind,” explained study author Alban Voppel, professor of AI and psychiatry at McGill University, in a statement. “Complete book-length texts written during an active psychotic episode are quite rare, giving us a unique opportunity to study language as the illness was unfolding.”

Voppel and his team ran what amounts to a computational linguistic autopsy on the diary, using tools that measure patterns in word use and sentence structure. Their question was a specific one: do the linguistic pathologies of formal thought disorders — a family that includes schizophrenia — show up in how topics are connected, or in the very words chosen to carry them?

Every autopsy needs a comparison, and theirs was carefully chosen: the foreword Nijinsky’s wife Romola wrote for the heavily edited version of the diary she published in 1936. The two texts are of similar length, from roughly the same period, on similar subjects — and Romola had no history of psychiatric illness.

What the analysis found was coherence of a strange, hollow kind. Nijinsky wrote in circles, returning to the same words again and again, which gave the text a superficial smoothness while the whole remained generally incoherent. “It’s sort of a fake coherence, a mechanical coherence,” Voppel said. “He came back to the same topics and used a lot of the same words, especially ‘I,’ ‘God’ and ‘love.’” Those words became the load-bearing members of the diary — the team wryly calls them the lettuce in his word salad.

The finding suggests something precise about how psychosis works on language: it operates at different levels at once. A person in the throes of acute mental illness may still build a broad narrative structure — sentences, themes reinforcement that orbits — even as the vocabulary available for the job narrows and narrows, pruned by the disorder down to a small set of words asked to carry everything.

> Nijinsky’s diary is not simply a document of suffering or a record of thought disorder; it is an unwitting self-portrait of a mind condensing around a fixed, narrow repertoire of words and the concepts they stand for.

There is one detail in all this that reads almost like a stage direction. The most celebrated dancer of his age — a man whose entire art consisted of meaning made without a single word — ended up documented by researchers as a writer clinging to just three of them: I, God, love.
